2 Claims.

The present invention relates to a new insulating material and to a new wall structure embodyingsuch insulating material. More particularly, the present invention relates to an insulating material which may be readily installed in wall structures which are designed to have air spaces, the present material serving to partition said air spaces, thereby multiplying the heat resistance of such air spaces several fold. By means of the preferred form of the present invention the heat resistance of the air space is still further increased by minimizing the transmission of radiated heat through such air spaces.

The insulating material I propose to use and the structures I propose to form will utilize the above principles and will form a very effective and efficient insulation, will be very easy to install, and can be fabricated very simply on a large scale and at a very low cost. This form of insulation can be applied to the walls and roofs of all types of building structures, and can be easily made to fit into all corners as under gabled roofs. This material will also be found to meet all requirements in the insulation of railroad cars, ships, refrigerator cabinets, automobile bodies, airplanes, cold storage Warehouses and other structures which require efficient and light weight insulation.

It will, therefore, be understood, that Wherever the term wall appears in the following specification and claims, it applies to all such structures which contain insulating air spaces.

In the drawing,

1 is a perspective view of -a roll of the material;

Fig. 2 is a perspective view of a severed portion of such material;

Fig. 3 isa sectional view of a portion of a wall having air spaces in which the present magreat facility so as to subdivide the air space into i a plurality of parallel air spaces. For this purpose, the web consists of several plies which are free of each other except along the edges and are so attached or associated that any length of the web may be severed and readily installed in an air space as by the attachment of the edges to the studding, beams, rafters, or other supporting members which are customarily part of the structure. The plies may be of any suitable material, such as building paper or the like, and in the preferred form the alternate plies are covered on one or both sides with a metal coating, such as metal foil, preferably aluminum foil, for the purpose of minimizing the transmission of radiated heat. Uncoated material may, of course, be employed if desired.

The material is preferably made available to the trade in roll form; nevertheless, when desired, it may be made available in severed lengths so that each such length may be said to constitute an insulation panel for installation in insulation spaces.

Fig. 1 shows one form of the'insulating mate rial. In this form the web 20 f insulating material form a roll 2|. The overall width of the web is somewhat in excess of the customary spacin of studding in a building frame. 1f the material is to be employed in other structures,

. then the width of the web 20 is somewhat greater than the spacing of the supporting members therein.

The web 2| consists of three plies 22, 23, 24, all of the same width. The outer plies 22 and 24 are each coated with metal or metal foil 29, preferably on both faces, and each has marginal strips 25 and 26, respectively, which are uncoated. The intermediate ply 23 is preferably uncoated and also has uncoated marginal strips 21. In each of the sheets crease lines 28 serve to facilitate the bending of such marginal strips during the installation of such webs and their attachment to the supports.

Each ply is attached to an adjacent ply only along one edge or marginal strip, the other edge remaining free in the case of outer plies, or, in the case of intermediate plies, the other edge is attached to the other adjacent ply. Ihus,.in the form shown herein, the outer ply 22 has one strip 25 free, and has its other strip 25 attached to the adjacent strip 21 in the intermediate ply 23,-which in turn has its other strip 21 attached to the strip 25 in the ply 24, while the opposite strip 26 is free. Thus, the plies are free of each other along their surfaces so as to provide air spaces bordered by such plies. The attachment between the strips 25 and 21 and between the strips 26 and 21 may be accomplished by staples 28 or by sewing, pasting, or in any other suitable manner.

The manner in which this material is employed now becomes apparent from the showing of Fig. 3 which is a schematic horizontal partial section of a wall and comprises studding 30, sheathing or siding 3| which may .be of any suitable material and wall board, plastic board or any other facing material 32. In the course of construction, studding 30, 40 is first erected and sheathing or siding 3| is then applied to the exterior of the studs. In the employment of the present material, before the inner facing 32 is applied, a suitable length of the material 20 is cut from the roll 2|, and installed in the space between the adjacent studs as shown in Fig. 3. The marginal strip 25 is tacked to the stud 30 at the far corner as shown. The intermediate marginal strips are tacked to studs 40 and 30 as shown, and the last free marginal strip 26 may be tacked on the face of stud 40 or on its side but adjacent the front face as desired. Thus, by means of the present material and with the aid of simple operations involving only a tacking operation, the large air space becomes divided into four smaller air spaces, thus substantially multiplying the heat resistance of the space four fold; and in addition the insulating material provides at least one face of metal for each air space, thereby substantially eliminating the transfer of radiated heat across such air spaces.

It will be understood that the material is employed in substantially the same manner in ceilings, in which case, 30 and 40 may be said to represent joists, and also in roofs in which case 30 and 40 may be said to represent rafters. The present material may thus .be employed in any and every insulating space.

It will also be understood that where the spaces happen to have peculiar shapes, the material 20 may be cut from the roll to suit the shape.

Under some circumstances, it may be sufficient merely to tack the free marginal strips as shown in Fig. 3 and leave the intermediate strips un- -tacked, for the material will occupy the condition shown in Fig. 3 even when the intermediate strips are untacked.

Fig. 4 shows another form of the invention. In this form the plies instead of being made of separate webs are all made of one wide web 4| which is divided into three longitudinal zones 42, 43, and 44. The zones 42 and 44 are each coated with metal foil 45 or with metal paint or with any other form of metallic coating for reflecting radiant heat on both faces while the intermediate zone 43 remains uncoated.

The web 4| is provided with the marginal strips 48, 41 which are preferably uncoated and are separated from the zones 42 and 44, respectively, by score lines 48 which facilitate the bending of such strips to the position shown in Fig. 5 preparatory to the installation of a severed portion of the web in an air space. If desired, additional suitable score lines 49, 50, and 5| may be provided so as to facilitate the bending of such portions to form intermediate attachment strips as shown in Fig. 3. Thus, an installation of a severed portion of the Web 4| will look the same as that shown in Fig. 3 except that the intermediate attachment strips are integral with each other.

Fig. 6 shows the use of this invention in an insulated cabinet. The material 13 is installed between the supporting members H and the outer and inner walls 12 and 14. The door 15 is similarly provided with the same insulation.

The present material, whether in the form shown in Fig. 1 or Fig. 4, is light in weight, is easy to manufacture, easy to handle and transport, readily manipulable for installation under all conditions, and the installation involves the simple tacking operation. All the forms shown herein may be employed either with orwithout the metal coating,

The present application is a division of my application Serial No. 196,981, filed March 19, 1940, now U. S. Letters Patent No. 2,251,585, dated August 5, 1941.

I claim:

1. An insulating material comprising a web of building paper in roll form, from which longitudinal portions may be severed for installation in the air spaces between the studs of a frame wall to partition this space into several air spaces disposed in series from one face of the wall to the other face, the web having a width greater than an integral multiple of the customary distance between adjacent studs, the web being divided by parallel longitudinal score lines into a plurality of coplanar panels, each panel having a width substantially greater than said distance, said score lines also serving for folding a severed portion of the web to dispose said panels in zigzag fashion with each panel having one edge united to one adjacent panel, the opposed edges of the outside panels being free and the opposed edge of an intermediate panel being free of said one adjacent panel and united to a second adjacent panel, each panel also having longitudinal marginal portions defined by additional score lines forming attachment strips for attachment to adjacent studs.

2. An insulating material set forth in claim 1 and having a metal coating on at least one face of some of said panels whereby radiation losses across said air spaces will be minimized.
